It's perhaps the most prestigious event in cinema held outside of Hollywood.

So it was no surprise to see the great and the good of the A-List pulling out all the stops on the opening night of the 70th Cannes Film Festival .

Making the most of the balmy weather in the South of France, the likes of Bella Hadid, Emily Ratajkowski competed with cinema's leading ladies Susan Sarandon and Julianne Moore to be the winner of the red carpet glamour stakes.

Bella Hadid - younger sister of fellow supermodle Gigi - managed to steal the show for a second year running, opting for a strapless pink gown with an extreme thigh-high split.

Following up on her famous red gown from the previous year, the 20-year-old runway queen straddled the line between high-fashion sass and old-school red carpet glamour.

Featuring an elegant trial and a sweetheart neckline, the satin number allowed Bella to ooze an old-school Hollywood siren vibe, whilst still flashing plenty of flesh.

However, the Californian beauty's dress was perhaps a little to risque, as she inadvertently flashed her underwear at one point.

She was seemingly oblivious to the fact her dress had bunched up behind her at one point, causing the gown to pull open, revealing her underwear.

And it would seem the problem wasn't just a slight malfunction, as the dress pulled open once again whilst she walked down the red carpet to greet Susan Sarandon.

She teamed her dress with a pair of matching strappy stilettos, which shifted the focus to her endless legs; whilst she topped things off with an eye-catching bejewelled necklace.

Oscar-winning actress Susan, 70, turned back the year's with an elegant black gown. Featuring an off-the-shoulder neckline, the Thelma and Louise star managed to straddle the line between demure and racy perfectly.
